[PATCH RFC v2 0/4] RISC-V: Add basic eMMC support for BeagleV Ahead

[Jiexun Wang]

Hello,
I tested the patch on my LicheePi 4A board.
It can successfully boot with eMMC, but when I use the eMMC more frequently - for instance:

$ while true; do /bin/dd if=/dev/zero of=bigfile bs=1024000 count=1024; done &

I encounter the following error:

My kernel version is v6.5-rc3.
My OpenSBI version is 1.3.
I tried to use other versions of OpenSBI, yet the problem persists. 
Is there a possibility of any underlying bug? Your insights into this would be greatly appreciated.

Thanks,
